• Figures I I to 14 show perspective, side, plan and perspective views of a container neck finish for use with the closure of Figures I to 10.
• Figures I to 3 show a closure generally indicated 10 connected to a container neck I .
• the closure 1 0 comprises a body 1 2, a plug member 20 and a tamper-evident member 5.
• the body 1 2 comprises a top plate 1 3 from which depends an upper sidewall 14.
• the top plate 1 3 is annular and includes a central hole 1 3a.
• the sidewall 14 is generally cylindrical and includes an internal annular bead 1 5 which projects radially inwards at a point axially displaced from the top plate.
• a generally cylindrical lower sidewall 1 6 continues from the upper sidewall 14.
• the side wall 1 6 terminates with an annular shoulder 1 6c which extends radially inwards and merges into the upper sidewall 14.
• the interior of the side wall 1 6 comprises internal screw thread formations 1 6a for engaging corresponding external screw thread formations 2 on the container neck located above a transfer bead 4.
• the interior of the side wall 1 6 further comprises an annular retention bead 1 6b positioned axially above the screw thread 1 6a.
• the plug 20 comprises a lower portion 50, a central portion 5 1 and an upper portion 52.
• the lower portion 50 comprises a ledge 2 1 with an annular seal 56 depending therefrom. In use, the seal 56 enters the bore of the container neck such that it seals against its inner surface.
• the ledge 2 1 comprises a plurality of radially outwardly extending retention spokes 60 at is periphery.
• the spokes 60 abut against the shoulder 1 6c.
• the spokes 60 are spaced from the bead 1 6b and that they terminate with a "claw" 6 1 that allows them to grip onto the rim 3 of the container neck I which comprises a peripheral bead 3a.
• the central section 5 1 includes an annular sidewall 52 and a flange 41 which projects radially outward from the side of the wall 52.
• the upper portion 52 comprises a sidewall 53 closed at one end by a top cover 54.
• the top cover extends into the top plate hole 1 3a.
• the tamper-evident member 5 takes the form of a separate element having an upper ring 6 and a lower ring 7 connected together by frangible connections 8.
• the tamper-evident member 5 fits into the sidewall 14 of the body 1 2, radially outward of the plug 20.
• the upper ring 6 includes an upper projection 6a which projects radially outwardly and engages under the sidewall bead 1 5.
• the lower ring 7 includes a flange 7a which projects radially inwardly and in the initially closed position of the closure shown in Figures I to 3 is located under the plug flange 41 .
• FIGS 4 to 9 the closure is shown being opened for the first time and then reclosed.
• Figures 4A and 4B show the closure 10 in the fully closed position, as described in relation to Figures I to 3.
• the closure is opened by unscrewing the body 1 2 from the neck I .
• the body is initially unscrewed it begins to move axially upwards, whilst the plug 20 remains in position.
• the member 5 moves upwards until the ring flange 7a contacts the plug flange 41 , as shown in Figures 5A and 5B
• the body is unscrewed further until the sidewall retention bead 1 6b contacts the spokes 60, as shown in Figures 7A and 7B. Further unscrewing causes the body to lift the plug, as shown in Figures 8A and 8B.
• the closure 10 can now be removed.
• the rings 6, 7 remain separated, as shown in Figures 9A and 9B.
• the body is non-opaque (for example translucent or transparent). This means that the separated rings are clearly visible.
• part of the body is non-opaque, or there is an opening/window formed in the body so that the at least one of the rings is visible/not visible in the initially unopened position and/or the reclosed position.
• the present invention provides an internal tamper- evident band for a flatcap, activated by unscrewing of the body from the neck.
• the closure moves from the appearance shown in Figure I OA to the appearance shown in Figure I OB.
• the closure is formed without a tamper-evident d rop band at the free end of the sidewalk This means that there is no requirement for a bead on the neck which would otherwise be required to engage under a d rop band and cause it to be broken away from the sidewalk As a result a neck finish 1 0 1 , for example, of the type shown in Figures I I to 1 4 is possible. This allows for weight reduction of the bottle neck and the closure and avoids issues of unwanted band breakage when the closure is applied to the neck.
• the neck finish 1 0 1 includes a transfer bead 1 04.
• the finish 1 0 1 is the part of the container that holds a cap or closure in use, and surrounds the opening 1 03 in the container. It is so named because, in early hand glass manufacturing, it was the last part of the glass container to be made, hence the term "finish"
• the exterior of the finish 101 includes a single start screw thread 105. In this embodiment this is a continuous spiral projecting ridge on the finish intended to mesh with the thread of a screw-type closure. Other screw thread formations, including multi-start threads, are possible.
• the transfer bead 104 is a continuous horizontal ridge near the bottom of the finish used in transferring of a container from one part of a manufacturing operation to another.
• the neck finish rim 106 includes an undercut 107.
